Answer:
Refer below for the explanation.
Step-by-step explanation:
As per the question we are asked to combine f(n) = 11 and g(n) = −2(n − 1), both of them to create arithmetic sequence and solve for 31st term.
So first we are about to solve and combine both of the equation which becomes ,
Fn = 11 -2(n-1)
Fn=11-2(n-1)
F31=-49
Fn=11-2(n-1)
F31=-51
Fn=11+2(n-1)
F31=71
Fn=11+2(n-1)
F31=73
